Definitions

  • the present invention relates to a disposable periodic towel for feminine hygiene. More particularly, the invention relates to a periodic towel with an absorbent core of elongated shape covered with a veil permeable to body fluids and comprising in the middle part of its upper face two series of discontinuous imprints, one of which is substantially parallel and adjacent to one of the longitudinal edges of the absorbent core and the other of which is substantially parallel to the opposite longitudinal edge of the absorbent core, thereby allowing good contact of the upper surface with the mucosa and better penetration of body fluids into the absorbent element and ensuring sufficient holding of the periodic towel, while leaving it a certain flexibility for the comfort of the user.
  • the absorbent structures applied in particular to feminine hygiene, such as periodic towels are composed in known manner, of an absorbent core of elongated shape covered with a veil permeable to body fluids, possibly hydrophobic, on the body side, and a waterproof sheet on the opposite side.
  • the coating can extend on the opposite side and also cover the waterproof sheet.
  • the coating can be a perforated film or a nonwoven and the impermeable sheet can for example be made of a polyethylene film.
  • the absorbent core is generally made up of cellulosic fibers such as paper fibers, called fluff, obtained by dry defibration of a sheet of paper pulp. It can also be made from sphagnum or any other absorbent material.
  • Such absorbent structures have been the subject of numerous studies aimed in particular at obtaining a clean and dry contact surface by appropriately choosing the coating material permeable to fluids and at improving their absorption properties by providing one or more channels on the upper surface of the absorbent core. Mention may respectively be made in this regard of EP-A-249405, US-A-3695269, US-A-3814101 and EP-A-172420, US-A-4184498 and EP -A-137725.
  • EP-A-173068 describes a periodic towel intended to alleviate both the two aforementioned defects of periodic towels of the prior art, that is to say the stained and / or wet appearance of the upper covering and poor distribution of fluids in the absorbent core.
  • the period towel described in EP-A-173068 comprises an elongated absorbent core having one face in contact with the body and one face in contact with the clothing, said absorbent core having, hollowed in its face in contact with the body, at least one groove elongated forming a channel having walls and a bottom for transporting bodily fluids, generally in the longitudinal direction; the sanitary napkin also has a hydrophobic coating permeable to bodily fluids covering one face in contact with the body comprising its hollow channel.
  • the periodic towel has a single channel placed in the center of the face in contact with the body.
  • GB-A-2114445 describes a periodic towel with absorbent means comprising a transfer layer composed of thermoplastic fibers and a main absorption layer, the whole being covered with a permeable veil. Connection zones in the transfer layer are provided to ensure the penetration of fluids.
  • the object of the present invention is to provide a periodic towel whose upper face, in contact with the body, keeps a clean and dry appearance during use and which has sufficient hold while retaining a certain flexibility for the comfort of the user.
  • a periodic towel of elongated shape having an upper face in contact with the body of the user and a lower face in contact with the undergarment of the user, comprising an absorbent core of elongated shape, delimited by longitudinal edges and transverse edges, said absorbent core being covered, on at least its upper face, with an absorbent veil permeable to body fluids and, on the lower face, with an impermeable sheet, its upper face comprising, in said lengthwise middle part, two sets of indentations, one of which is adjacent to one of said longitudinal edges of said absorbent core and the other of which is adjacent to the opposite longitudinal edge of said absorbent core, characterized in that that said imprints are discontinuous, and that said two series take up the entire thickness of the core and thus create between them a swelling of the absorbent core on which the permeable veil is stretched.
  • each of said imprint series is substantially parallel to the longitudinal edge of said absorbent core to which it is adjacent.
  • the two sets of imprints can extend into almost the entire middle part, when wearing the towel, in the crotch region of the wearer's undergarment or extend below the zone delimiting said middle part.
  • the absorbent core of the sanitary napkin has an anatomical shape in which said middle part is narrowed.
  • the longitudinal edges of the absorbent core each have a curved portion, forming a biconcave zone in said middle part.
  • the imprints according to the invention can have any shape. They can for example be substantially rectangular, circular, etc.
  • the imprints of each of said series can be identical or different.
  • each of the series of imprints consists of a succession of alternating linked and non-linked zones.
  • the series of discontinuous imprints according to the invention have the effect of creating a bulge in said median part of the periodic towel giving a pronounced convexity to its upper face, ensuring good contact with the mucosa, and of stretching the fluid-permeable veil which improves their penetration into the absorbent core.
  • the series of discontinuous fingerprints according to the invention also have the effect of ensuring good performance of the periodic towel, while leaving it with sufficient flexibility for the comfort of the user.
  • the imprints according to the invention can be formed by any suitable means, for example by implementing a method as described in FRA-A-2590161 using several lugs each having the shape of the desired imprint.
  • the invention will now be illustrated in more detail with reference to Figures 1, 2 and 3 attached.
  • Figure 1 is a top view of an anatomical periodic towel according to a preferred embodiment of the invention.
  • Figure 2 is a cross-sectional view along line II-II of Figure 1.
  • Figure 3 is a cross-sectional view along line III-III of Figure 1.
  • a periodic towel (1) of elongated shape having an upper face (2) in contact with the mucosa and a lower face (3) in contact with the undergarment.
  • the period towel (1) comprises an absorbent core of elongated shape (4) delimited by longitudinal edges (5) and (5 ′) and transverse edges (6) and (6 ′).
  • the longitudinal edges (5) and (5 ′) each have a curved portion forming a biconcave zone in the middle part of the period towel (1).
  • the absorbent core is covered with an absorbent veil (7) permeable to body fluids and on its underside and it is covered with an impermeable sheet (8).
  • the absorbent web (7) completely surrounds the absorbent core, also covering the impermeable sheet (8), their transverse edges being sealed in the parts (11) and (11 ′).
  • the absorbent web (7) has a width greater than that of the absorbent core in the biconcave zone, defining lateral flaps (12) and (12 ′) which are welded together and include folds (13) and (13 ′).
  • a longitudinal protective strip (14), detachable during use, is fixed, by means of adhesion elements (15) on the underside (3) of the period towel (1).
  • the upper face (2) of the sanitary napkin (1) comprises in the middle zone two series (9) and (9 ′) of imprints (10) and (10 ′) discontinuous, represented here with a substantially rectangular shape, of which one (9) is adjacent to the longitudinal edge (5) and the other (9) is adjacent to the opposite longitudinal edge (5 ′).
  • a bulge is created in the middle part of the absorbent core (4) giving a pronounced convexity to the upper face (3) of the sanitary napkin (1) in said middle part.
